Recent delicate scientific expert
ments have discovered the fact that the
surface of the land is never absolutely
at rest for more than thirty hours at
time. Thus, those great earthquakes
which make epochs in history are mere
ly extreme cases of forces that seldom
sleep.-Pubtic Opinion.
How much rain must fail in the
coarse of the day to make it a rainy
day in the meteorological senseP This
question has been discussed a good
deal by persons interested in weather
| science, bat not yet determined authori-

to be that a rainfall amounting at
least to the one-hundredth part of an
| inch is necessary to make a rainy day.

"A French savant has propounded
theory that coal was originally a liquid
generated by the decomposition of in
ferior vegetation in an atmosphere
highly charged with carbonic acid.
The carbon of the jelly-like mass just
formed, after passing through various
transformations into asphalt, petrol
cum, bitumen, ETC., finally assumed the
form of coal. The author cites various
facts connected with the occurrence of
coal which, he thinks are better ex-
planned on this theory than by the
usual one. Public Opinion.
Mr.. Desire Chamay, the Central
American traveller, asserts that the
concentric circles shown in logs CT ma
hogany, and many other tropical woods
correspond to so many months of
growth, rather than to one year each,
as is generally supposed. I'm my first
expedition to Palenque," he says, 'in
1859, l had the east side of the palace
cleared of its dense vegetation, to Sc

ly the trees that have grown up since
| Cup to 1892 can not be more than
twenty-five years old. Now, one of
the cuttings, measuring some two feet
in diameter, had upward of two humid

The Mississippi Valley Lunabernaa's
thinks that the output of the mills on
streams tributary to the Upper Missis-

But the same lack of rain has dimin-
ished the ability of the farmers, and of
those who live by trading with the
farmers, tc buy lumber, to almost an
equal extent in a considerable part of
the region to which the lumber is COM
monty sent. Indeed, an amount of
rainfall which would materially benefit
crops would, especially after long
drought, do almost nothing to start
"hung-up'' logs down stream.
